For municipal waterworks supervisors, keeping curb boxes in good working order is critical. But this job can become even more complicated by the prevalence of acidic soils across the U.S., which accelerates corrosion along with costly repair and replacement.
Every water system typically consists of piping networks that distribute water from a source or storage reservoir to the end users. This usually will require some form of a valve that will have to be controlled.
District Sales Engineer Andy Singer has spent enough time troubleshooting problems in the field that not much surprises him anymore. When it comes to dry barrel fire hydrants, though, he still gets a chuckle out of some of his more outrageous experiences. Here is his educational and entertaining take on the care and maintenance of fire hydrants, and ways to maximize a utility’s return on what potentially can be a 50+-year infrastructure investment.
Bethpage Water District’s (New York) outdated water metering system led to customer service concerns, such as a slow response time for detecting leaks and insufficient data for billing inquiries.
Non-revenue water (NRW) and, in particular, water loss through leakage has become an increasing priority focus for water utilities around the world. With failure rates of aging infrastructure increasing and growing water stress due to population growth and climate change, reducing the loss of essential water resources is paramount. Leak monitoring and detection systems from Trimble Water help water utilities proactively identify and reduce NRW and water loss, prevent service outages, and prioritize infrastructure repairs. Easy-to-use wireless and mobile leak detection solutions provide clear, accurate, real-time insights into the condition of the water network beyond the treatment plant. Paired with Trimble’s intuitive cloud-based GIS software, Trimble’s solutions make it simple for water professionals to visualize, manage, and analyze data from the field and use that knowledge to improve productivity and network performance.
As with most things in life, there are those water utilities that have and those that don’t. According to the EPA, less than 3% of the 150,110 operational public water systems (PWS) in the U.S. serve more than 10,000 people. And those 4,500 systems serve 79% of the population. Not that being big means living trouble free. Many of these water authorities serve cities plagued by under investment over decades in their water systems. And yet with large rate-bases comes the means to spread the investment in modern technology across many households and water consumers.
Reducing water loss and saving money are two of the highest priorities—and most consistent challenges—facing water professionals. Both of these issues stem from water pressure control.
Every city facing infrastructure or operational challenges or concerns about maintaining quality of life in the face of population growth or a changing environment has benefits to gain from a unified smart-city approach. Here are some concepts for promoting understanding and acceptance among utility and government decision-makers, plus several examples of benefits already being garnered by smart cities large and small.
A small water district in Breckenridge, CO, was experiencing notably high water loss from November of 2015 through April of 2016. The apparent discrepancies in usage versus production led the utility to seek out the source(s) of the water loss.
Electromagnetic meters (mag meters) are well established in terms of highly accurate performance for a variety of municipal and industrial water applications. Differences in their construction formats, however, dictate how easy they can be to install, maintain, and calibrate. Compare these three options to see the value of full-profile-insertion (FPI) mag meters and their associated advantages in real-world use.
Providing large cities with drinking water is never an easy task. Outdated systems can cause problems such as leakages or contaminations.
Virtually all industries from food and beverage to chemical processing use heat exchangers, condensers,or jacketed vessels. Leakage of the process into the cooling water represents a loss of product and can be a source of fouling or corrosion in the cooling water system.
The HR-E LCD encoder has a 9-digit Liquid Crystal Display (LCD) to show consumption, flow and alarm information. The display automatically toggles between 9-digit and 6-digit consumption, rate of flow and meter model.
A new pipe-repair solution promises to save time and money, while also being sustainable, long-lasting, fully scalable, and safe for workers.
Pressure reducing valves (PRVs) are used throughout water distribution systems to reduce pipeline pressure to a predetermined set point. This decreases water loss and prevents pipe breaks.
The simplicity of the compact, battery-powered Telog HPR-31 enables you to put it to work within minutes of unpacking. Once installed, the Telog HPR-31 measures water pressure at user programmable rates up to four samples per second with its internal pressure transducer. You can determine how often such data is summarized for reporting. The recorder computes any combination of minimum, average and maximum pressure measurement at each interval according to your selection of statistics and recording intervals. Recorded data may be gathered via an RS-232 connector using a handheld device or a laptop.
The pressures of supplying a growing global population mean that the world’s water supplies need to be managed more closely than ever.
Some wastewater applications require chlorine residuals greater than can be effectively monitored using DPD due to the oxidation of the Wurster dye to a colorless Imine. Such applications include industrial wastewater processes that inherently have a high chlorine demand thereby requiring a more robust monitoring method.
Denver Water and engineering partners resolve major water quality challenge in crucial South Platte River exchange reservoirs.
The lessons of Flint should be well heeded, and lead mitigation continued, but the big-picture story of lead exposures in the U.S. is a tale of tremendous progress.
Most utilities understand they have a nonrevenue water problem, but few know how to deal with it correctly. Start by learning more about how the issue affects your utility and what options are available.
University of Miami professors who study water treatment and civil engineering say that water contamination issues point to human error.
Recently, Denver Water’s board approved its proposed “Lead Reduction Program Plan” to fully replace the estimated 75,000 lead service lines (LSLs) in their system within 15 years. The plan is an innovative solution that will remove the primary source of lead within Denver Water’s system, while avoiding the use of orthophosphate that can further exacerbate nutrient pollution problems in rivers, streams, and oceans.
